File An Appeal

How To Appeal

If you feel your property is over-assessed, you have the right to file an appeal with the Board of Review. The Board of Review accepts appeals from property owners by townships which open for appeals for a limited period. To file an appeal with the Board of Review, simply fill out a complaint form and return it to the Board of Review before your township’s appeal period is closed. Commissioner Cabonargi’s staff will research the appeal and prepare evidence for the Board to review and make a decision. You can also file an appeal in person at the Board of Review or at a satellite office. Please refer to the website for addresses and operating hours.

How To Appeal Online

In 2011, the Board of Review introduced a new online appeal filing system. Now property owners may file an appeal online through the Board of Review’s website (www.cookcountyboardofreview.com). A property owner may also preregister an appeal before their township opens. For more information please visit www.cookcountyboardofreview.com. To learn when your township opens and closes for appeals or for more information about the appeals process, please contact Commissioner Cabonargi’s office at (312) 603-5560.

Grounds for Appeal

There are several grounds for appealing your assessment, including, but not limited to:

Comparable properties near your property are assessed at values lower than yours

Factual errors in the description of the property, including incorrect square footage and/or characteristics

Damage caused by fire, flood, or other casualty, or property that has been wholly or partly demolished

The property was recently purchased for less than the Assessor’s fair market value of the property
